For they are always threatening other states with war by appearing to be in constant readiness to fight. They incite the various states to outrival one another in the number of their soldiers, and to this number no limit can be set. Now, since owing to the sums devoted to this purpose, peace at last becomes even more oppressive than a short war, these standing armies are themselves the cause of wars of aggression, undertaken in order to get rid of this burden. To which we must add that the practice of hiring men to kill or to be killed seems to imply a use of them as mere machines and instruments in the hand of another (namely, the state) which cannot easily be reconciled with the right of humanity in our own person.[113] The matter stands quite differently in the case of voluntary periodical military exercise on the part of citizens of the state, who thereby seek to secure themselves and their country against attack from without. [113] A Bulgarian Prince thus answered the Greek Emperor who magnanimously offered to settle a quarrel with him, not by shedding the blood of his subjects, but by a duel:—“A smith who has tongs will not take the red-hot iron from the fire with his hands.” (This note is a-wanting in the second Edition of 1796.
